Raine Sage is Genis Sage's older sister and teacher of the school house in Iselia. She is a very strict teacher but is also very kind and motherly. When Collete received the oracle it was established that she and Kratos Aurion would accompany her on the journey of world regeneration. This plan fell apart when Genis and Lloyd Irving catch up with them and join their group. Raine is also an archeologist and becomes obsessed when she find any ruins, going into a mode described by the group as "Ruins Mode". Raine is accomplished in healing arts as well as powerful light elemental magic spells. In battle, if Raine is not controlled by a human player she will usually stay away from the fight and cast spells until she runs out of TP. Raine fights with a staff that while useful for spellcasting, it isn't as effective in close ranged combat.
